The push for a much more restrained US foreign policy, whether in the Middle East (as Gregory Gause argued) or around the world (as Stephen Walt would have it) makes eminent sense. But if pundits and policymakers are serious about moving the United States in that direction, it is going to require challenging two core beliefs: American exceptionalism and conditional sovereignty. Without challenging these pillars of American interventionism run amok, any shift toward restraint will be shallow and temporary.
The rise of the United States as a global power may have come about because of economic might, technological innovation, and military prowess, but it has also been intimately linked to a can-do attitude and a perception of inherent superiority. While a realist might emphasize that growth in US material power and what the US can do (see Monteiro here), we need to recognize that it has been married to an ideational commitment to using that power. From the moment the colonists prevailed over the mighty British Empire, this was a country that could overcome great odds and re-make the world in its image. We are the city on a hill, the arsenal of democracy, the indispensable nation. The American way is the best way.
